Key result
Multiscale simulations identify a conserved PIP2-binding site on the M0 helix across three Kir channels.
Why the study?
The specific PIP2-binding sites on mammalian Kir channels and their molecular interactions were not fully defined.
Population
Three Kir channel structures: KirBac1.1, Kir3.1-KirBac1.3 chimera, and Kir6.2 homology model
Comparison
Multiscale simulations combining coarse-grained and atomistic molecular dynamics
Design
Preclinical molecular dynamics simulation study

Simulations map PIP2 sites on Kir channels; leaves open their role in cardiac K+ currents and requires functional validation.
Multiscale biomolecular simulations identified a conserved PIP2-binding site at the N-terminal end of the slide (M0) helix in Kir channels, providing structural insights into channel activation.
Stansfeld et al. (2009) studied this question. Multiscale biomolecular simulations was evaluated on Identification of PIP2-binding site on Kir channels. Multiscale biomolecular simulations identified a conserved PIP2-binding site at the N-terminal end of the slide (M0) helix across three Kir channel structures.
